Nolan talks about how he loves films like Blade Runner that "create a reality beyond the frame" and he tries to do that with his films. The newspaper thing is a perfect example. There are so many little set design things that didn't even make the film (or at least I don't think they did). The Bane propaganda stuff, the Blackgate dedication to Dent, The Wayne Enterprises sign on Trump Tower etc. The reality of the film is much larger than what actually lands on screen, and I think that's very much a part of Nolan's overall M.O.
